Persons interested in being placed on a mailing list for future NPRM’s should contact the FAA’s Office of Rulemaking, (202) 267–9677, for a copy of Advisory Circular No. 11–2A, Notice of Proposed Rulemaking Distribution System, which describes the application procedure. The Proposal

The FAA is proposing an amendment to Title 14 Code of Federal Regulations (14 CFR) part 71 by modifying Class D airspace, and Class E airspace designated as an extension to Class D surface area, and airspace extending upward from 700 feet above the surface, at Fort Huachuca, AZ. This action was initiated by the FAA’s biennial review of the airspace, in which they found additional controlled airspace necessary for the safety and management of aircraft departing and arriving under IFR operations at Fort Huachuca, Sierra Vista Municipal Airport-Libby Army Airfield. This action would also update the geographic coordinates and the airport name from Fort Huachuca, Libby AAF/Sierra Vista Municipal Airport, to Fort Huachuca, Sierra Vista Municipal Airport-Libby Army Airfield.

Class D airspace and Class E airspace designations are published in paragraph 5000, 6004 and 6005, respectively, of FAA Order 7400.9U, dated August 18, 2010, and effective September 15, 2010, which is incorporated by reference in 14 CFR 71.1. The Class D airspace and Class E airspace designation listed in this document will be published subsequently in this Order.

The FAA has determined this proposed regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this proposed regulation; (1) is not a ‘‘ significant regulatory action ’’ under Executive Order 12866; (2) is not

a ‘‘ significant rule ’’ under DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified this proposed rule, when promulgated, would not have a significant economic impact on a

substantial number of small entities under the criteria of the Regulatory Flexibility Act.

The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the U.S. Code. Subtitle 1, section 106, describes the authority for the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency’s authority. This rulemaking is promulgated under the authority described in subtitle VII, part A, subpart I, section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of the airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it creates additional controlled airspace at Fort Huachuca, Sierra Vista Municipal Airport-Libby Army Airfield, Fort Huachuca, AZ.
